Improvement in cans for oil

IMPROVEMENT IN Specification formingpart of Letters Patent No.

To all whom it may concern:

Be it known that ILQEQLHLQHTIENQQKLQ Brooklyn, in thezdulnty of Kings and State of New York, have invented certain Improvements in Paper Oil-Cans, oi' which the following is a specification:

This invention consists in certain novel combinations of' parts, whereby is provided a paper can for holding oils, which shall be tight and impervious, strong and durable, not

liable to warp, twist, or be otherwise injured from changes in the temperature, or hygrometric conditions oi' the atmosphere, and capable of storage and transportation within the smallest possible space.

Figure l is a plan view of a paper oil-can, made according to my invention. Fig. 2 is a vertical transverse section of the same; and Fig. 3 is a detached sectional view on a large scale, showing one feature of the invention not clearly indicated in Figs. l and 2.

The body A of the ca n is rectangular or four-sided, but with rounded corners, as shown at a. It is formed of distinct concentric thicknesses b, of paper or paper-board, made oil-proof, or oil and water proof, by saturation with a solution of glue, which after its application to the paper material should be rendered insoluble by treatment with a solution of tannin. Of the several thicknesses b, the innermost is the shortest, the thicknesses increasing in length from the innermost outward, so that the end edges of the body A are related, asfully shown inFig. 2. The heads B are of prepared wood-that is to say, of wood subsequently steamed and impregnated with glue, or treated in other ways, to prevent the permeation of hydrocarbon oils therethrough, and the warping and twisting which, with the unprepared material, would occur from atmospheric changes. In lieu of wood from planks or lumber, sawdust or other like ligneous material, mingled with glue and compressed to hardness by suitable machinery, may be used. The heads are rabbeted to correspond with the end edges of the body A, and t therein, as shown in the sectional view, the adjacent end of the outermost thickness of papermaterial surrounding the periphery of each head, to permit the driving in of wooden pegs a', to assist the retention of the cANs FoRvvolL, ec.

153,662, dated August 4, 1874; application led heads in place. The zigzag joint c, between A, into which they are fitted, is iilled between with the elastic or yielding composition of which printers rollers are made. This elastic joint, while perfectly tight against the passage ofthe oil, is yet soyielding that j arrin g and concussion, which would start a rigid joint and causeleakage, are wholly inadequate to injure this elastic one. Placed within the body A, longitudinal therewith, and with their ends bearing against the inner surfaces of the heads B, are braces C, ofv any suitable wood. These braces'may iit into recesses provided in the heads, and 'pegs c may be driven through the latter into the ends of the braces. These braces serve to stiien the can against pressure from without, and also to hold the heads against outward thrusts. It will be particularly kept in mind that the corners a of the paper body A being rounded, as set forth, the tendency to crack, which would nullify the utility of a paper can made square-cornered or sharp-cornered, is wholly avoided also, that the pegs a will not corrode, and con sequently loosenand permit the displacement of the head, as would be the case if metal nails were used. The outermost thickness, b, of paper material, is extended upward beyond @the outer surface of the head, and within it and upon the head is iixed a circumferential rib, f', to which, at a level below the projecting end of the aforesaid thickness b, is aiixed the strap or handle g, by which, on occasion, the can is carried. This arrangement of the parts permits the cans, in storing or transportation, to be placed upon one another without detriment to their stability, when arranged 1n position. The lower end of the outermost thickness b is also projected beyond its contiguous head, and has within it and attached to the head a peripherical rib, m, which forms an annular foot or step to the can, which, by keeping the bottom or lowermost end of the transported, prevents the premature decay thereof', and consequently the leaking or destruction of the can.

What I claim as my invention is 1. Thecombination, with the heads and the paper body of an oil-can, of the internal longican from damp floors, &c., when stored orl
